Psychological disorders and coping strategies in patients with inflammatory bowel disease. Their impact on health-related quality of life.

BACKGROUND AND OBJECTIVES: inflammatory bowel disease (IBD) has a major impact on psychological well-being. This condition is associated with a high level of anxiety and mood disorders, but stress prevalence and how an individual copes with IBD have not been sufficiently explored. The objective of this study was to assess the impact of the disease on psychological disorders and to identify coping strategies used by patients with IBD, as well as to analyze the relationship between these variables and sociodemographic and clinical variables. METHODS: a cross-sectional prospective study was performed including 126 consecutive patients. Those with psychiatric conditions prior to the onset of the IBD were excluded. Independent variables were measured using a sociodemographic and clinical questionnaire. The patients completed the Hospital Anxiety and Depression Scale (HADS), the Perceived Stress Scale (PSS) and the BRIEF COPE questionnaire. Quality of life was measured using the nine-item IBD Quality of Life (IBDQ-9). RESULTS: the final cohort comprised 100 patients (37 with ulcerative colitis and 63 with Crohn's disease). The prevalence rates of the variables of stress, anxiety and depression were high (44 %, 24 % and 14 %, respectively). Stress and depression were higher in females (p < 0.05), without differences regarding other sociodemographic and clinical variables. Moreover, higher levels of anxiety and depression were found to be associated with stress and dysfunctional coping strategies (p < 0.01). CONCLUSIONS: patients with IBD, particularly women, have high rates of psychological disorders. Those with anxiety and depression presented more stress and used more dysfunctional strategies. These conditions must be considered for a multidisciplinary management.

First case report of multivisceral transplant from a deceased cardiac death donor.

The current shortage of pediatric multivisceral donors accounts for the long time and mortality on the waiting list of pediatric patients. The use of donors after cardiac death, especially after the outbreak of normothermic regional perfusion, has increased in recent years for all solid organs except the intestine, mainly because of its higher susceptibility to ischemia-reperfusion injury. We present the first literature case of multivisceral donors after cardiac death transplantation in a 13-month-old recipient from a 2.5-month-old donor. Once exitus was certified, an extracorporeal membrane oxygenation circuit was established, cannulating the aorta and infrarenal vena cava, while the supra-aortic branches were clamped. The abdominal organs completely recovered from ischemia through normothermic regional perfusion (extracorporeal membrane oxygenation initially and beating heart later). After perfusion with the preservation solution, the multivisceral graft was uneventfully implanted. Two months later, the patient was discharged without any complications. This case demonstrates the possibility of reducing the time spent on the waiting list for these patients.

Preclinical Study of DCD and Normothermic Perfusion for Visceral Transplantation.

Considering recent clinical and experimental evidence, expectations for using DCD-derived intestines have increased considerably. However, more knowledge about DCD procedure and long-term results after intestinal transplantation (ITx) is needed. We aimed to describe in detail a DCD procedure for ITx using normothermic regional perfusion (NRP) in a preclinical model. Small bowel was obtained from pigs donors after 1 h of NRP and transplanted to the recipients. Graft Intestinal samples were obtained during the procedure and after transplantation. Ischemia-reperfusion injury (Park-Chiu score), graft rejection and transplanted intestines absorptive function were evaluated. Seven of 8 DCD procedures with NRP and ITx were successful (87.5%), with a good graft reperfusion and an excellent recovery of the recipient. The architecture of grafts was well conserved during NRP. After an initial damage of Park-chiu score of 4, all grafts recovered from ischemia-reperfusion, with no or very subtle alterations 2 days after ITx. Most recipients (71.5%) did not show signs of rejection. Only two cases demonstrated histologic signs of mild rejection 7 days after ITx. Interestingly intestinal grafts showed good absorptive capacity. The study's results support the viability of intestinal grafts from DCD using NRP, contributing more evidence for the use of DCD for ITx.

Is cervical dysplasia a major concern in women with inflammatory bowel disease? A Spanish retrospective study.

Cervical cancer (CC) is the fourth most common cancer affecting women worldwide. The risk of women immunosuppressed due to AIDS or organ transplantation is well documented, as most cases are caused by persistent human papillomavirus (HPV) infection and immunosuppression can prevent clearing HPV. Although European guidelines advise that inflammatory bowel disease (IBD) women under immunosuppression should be screened for CC as regularly as high-risk patients, quality evidence is lacking in our country. We performed a retrospective case-control (2020-2021) study to analyse the risk factors associated with the appearance of low-grade (LSIL) or high-grade (HSIL) squamous intraepithelial cervical lesions in patients with IBD. We included all women aged 21-65 years , followed up at the University Hospital Fundación Alcorcón (Spain). Cases were defined as those patients with abnormalities in cervical cytology, while the control group consisted of the rest of the women. Disease characteristics, treatments and epidemiological data (smoking habit, sexual behaviour and reproductive history) were obtained. We documented the evolution of abnormalities over time and compare data between women under immunosuppressive treatment or not.

ß-blockers and ACE inhibitors are not a risk factor for severe systemic sting reactions and adverse events during venom immunotherapy.

BACKGROUND: There is controversy whether taking ß-blockers or ACE inhibitors (ACEI) is a risk factor for more severe systemic insect sting reactions (SSR) and whether it increases the number or severity of adverse events (AE) during venom immunotherapy (VIT). METHODS: In this open, prospective, observational, multicenter trial, we recruited patients with a history of a SSR and indication for VIT. The primary objective of this study was to evaluate whether patients taking ß-blockers or ACEI show more systemic AE during VIT compared to patients without such treatment. RESULTS: In total, 1,425 patients were enrolled and VIT was performed in 1,342 patients. Of all patients included, 388 (27.2%) took antihypertensive (AHT) drugs (10.4% took ß-blockers, 11.9% ACEI, 5.0% ß-blockers and ACEI). Only 5.6% of patients under AHT treatment experienced systemic AE during VIT as compared with 7.4% of patients without these drugs (OR: 0.74, 95% CI: 0.43-1.22, p = 0.25). The severity of the initial sting reaction was not affected by the intake of ß-blockers or ACEI (OR: 1.14, 95% CI: 0.89-1.46, p = 0.29). In total, 210 (17.7%) patients were re-stung during VIT and 191 (91.0%) tolerated the sting without systemic symptoms. Of the 19 patients with VIT treatment failure, 4 took ß-blockers, none an ACEI. CONCLUSIONS: This trial provides robust evidence that taking ß-blockers or ACEI does neither increase the frequency of systemic AE during VIT nor aggravate SSR. Moreover, results suggest that these drugs do not impair effectiveness of VIT. (Funded by Medical University of Graz, Austria; Clinicaltrials.gov number, NCT04269629).

The COVID-19 pandemic shows us in which way the care of patients with inflammatory bowel disease should move.

The COVID-19 pandemic has forced major changes in the care of patients with inflammatory bowel disease (IBD). The articles by El Hajra et al. and Fernández Álvarez el al. show the modifications in patient management that were performed during the state of alarm in Spain.

Comparison of original and biosimilar infliximab (CTP-13) in biologic-naïve patients with Crohn's disease and ulcerative colitis: a retrospective, multicenter real-life study in Spain.

PURPOSE: biosimilar infliximab (CTP-13) has been recently approved for the treatment of several immune-mediated inflammatory disorders, including inflammatory bowel disease (IBD). Comparative studies between this biosimilar and original infliximab in the real clinical practice are scarce. The objective of this study was to compare short and long-term safety and efficacy of original (O) and biosimilar infliximab (B-IFX) in biologic-naïve, IBD patients in the real life clinical practice. METHODS: a retrospective, multicentric study was performed in five Spanish hospitals. Consecutive IBD, biologic-naïve patients from an historic cohort who initiated O-IFX from January 2013 were compared with biologic-naïve patients, who started treatment with B-IFX since its approval in January 2015. The evaluation of efficacy was assessed after the induction phase, at week 14 and week 54 of treatment. Time to dose escalation or treatment persistence of both O-IFX and B-IFX was also considered. The appearance of serious adverse events was recorded. RESULTS: two hundred and thirty-nine IBD biologic-naïve patients who started with O-IFX or B-IFX were included: 153 patients were diagnosed with Crohn's disease (95 treated with O- and 58 treated with B-IFX) and 86 with ulcerative colitis (40 received O- and 46 received B-IFX). At weeks 14 and 54, both O-IFX and B-IFX groups reached a similar clinical response and remission rates. Time to dose escalation, treatment persistence and safety profile were comparable between both groups. CONCLUSIONS: this long-term real-life experience provides additional evidence of the similarity of O- and B-IFX CTP-13 in terms of efficacy and safety in IBD patients.

Autoimmune hepatitis, primary sclerosing cholangitis, and inflammatory bowel disease. Sequential overlap syndrome: a twist to the mosaic of autoimmunity.

Autoimmune liver diseases can overlap resulting in a new entity, phenotypically different from those pathologies that converge, and that demonstrates the complexity of our immune system. Sequential overlap syndrome is the consecutive presentation, separated by a variable period of time, of two liver autoimmune diseases, mostly autoimmune hepatitis and primary biliary cholangitis. This syndrome constitutes a challenge both in its diagnosis and in its treatment given the exceptional nature of its presentation. The theory of a mosaic of autoimmunity is proposed to describe this phenomenon.

Successful management of anemia with sirolimus in blue rubber bleb nevus syndrome: case report and update.

Blue rubber bleb nevus syndrome (BRBNS) is a rare disorder with characteristic skin hemangiomas and vascular malformations, mostly in the gastrointestinal (GI) tract. The GI lesions are mainly located in the stomach and small intestine, usually more than a hundred, leading to gastrointestinal bleeding and severe chronic anemia. Parenteral iron infusions and scheduled transfusions are frequently necessary. We describe the case of a 21-year-old male with anemia secondary to BRBNS, who becomes unresponsive to octreotide and shows an excellent response to sirolimus (SRL), dismissing the intravenous iron supplementations and being free of transfusions. During the treatment, the patient presents avascular hip necrosis, which is adequately treated with an injection of stem cells with complete recovery, and without the suspension of SRL. Two years later, adequate response persists with no other relevant side effects.

Adalimumab Maintenance Treatment in Ulcerative Colitis: Outcomes by Prior Anti-TNF Use and Efficacy of Dose Escalation.

BACKGROUND: The impact of prior anti-TNF use on "real-life" outcomes of adalimumab therapy in ulcerative colitis (UC) is not well known. AIM: To compare the influence of prior anti-TNF use on the outcomes of adalimumab maintenance treatment in UC patients. We also assessed the effectiveness of adalimumab dose escalation. METHODS: This retrospective multicenter cohort study included consecutive UC who advanced to an adalimumab maintenance regimen. Patients in whom adalimumab was discontinued prior to week eight of treatment were excluded. The co-primary efficacy endpoints were the cumulative probabilities of adalimumab failure-free survival and colectomy-free survival. We also assessed the need for and the effectiveness of adalimumab dose escalation. RESULTS: Of 184 UC on maintenance treatment with adalimumab, 116 (63%) had previous anti-TNF use. After a median follow-up of 23 months (interquartile range 13-49), 112 patients (60%) maintained corticosteroid-free clinical response. Sixty-nine patients (37%) had adalimumab failure, and 22 (12%) needed colectomy. Anti-TNF-naïve patients had significantly lower adjusted rates of adalimumab failure (hazard ratio [HR] 0.65; p < 0.001), adalimumab dose escalation (HR 0.35; p = 0.002), and need for colectomy (HR 0.26; p < 0.004). Seventy-six patients (41%) needed dose escalation after secondary loss of response, and 47% of these regained response after escalation. Short-term response after escalation was identified as a significant predictor of colectomy avoidance (HR 0.53; p = 0.007). CONCLUSIONS: In this "real-life" cohort of UC patients on maintenance treatment with adalimumab, anti-TNF-naïve patients had significantly better long-term outcomes. Adalimumab dose escalation enabled recovery of response in nearly half of patients.

Impaired oxidative metabolism and calcium mishandling underlie cardiac dysfunction in a rat model of post-acute isoproterenol-induced cardiomyopathy.

Stress-induced cardiomyopathy, triggered by acute catecholamine discharge, is a syndrome characterized by transient, apical ballooning linked to acute heart failure and ventricular arrhythmias. Rats receiving an acute isoproterenol (ISO) overdose (OV) suffer cardiac apex ischemia-reperfusion damage and arrhythmia, and then undergo cardiac remodeling and dysfunction. Nevertheless, the subcellular mechanisms underlying cardiac dysfunction after acute damage subsides are not thoroughly understood. To address this question, Wistar rats received a single ISO injection (67 mg/kg). We found in vivo moderate systolic and diastolic dysfunction at 2 wk post-ISO-OV; however, systolic dysfunction recovered after 4 wk, while diastolic dysfunction worsened. At 2 wk post-ISO-OV, cardiac function was assessed ex vivo, while mitochondrial oxidative metabolism and stress were assessed in vitro, and Ca(2+) handling in ventricular myocytes. These were complemented with sarco(endo)plasmic reticulum Ca(2+)-ATPase (SERCA), phospholamban (PLB), and RyR2 expression studies. Ex vivo, basal mechanical performance index (MPI) and oxygen consumption rate (MVO2) were unchanged. Nevertheless, upon increase of metabolic demand, by ß-adrenergic stimulation (1-100 nM ISO), the MPI versus MVO2 relation decreased and shifted to the right, suggesting MPI and mitochondrial energy production uncoupling. Mitochondria showed decreased oxidative metabolism, membrane fragility, and enhanced oxidative stress. Myocytes presented systolic and diastolic Ca(2+) mishandling, and blunted response to ISO (100 nM), and all these without apparent changes in SERCA, PLB, or RyR2 expression. We suggest that post-ISO-OV mitochondrial dysfunction may underlie decreased cardiac contractility, mainly by depletion of ATP needed for myofilaments and Ca(2+) transport by SERCA, while exacerbated oxidative stress may enhance diastolic RyR2 activity.

Prevalence of Steinert's Myotonic Dystrophy and Utilization of Healthcare Services: A Population-Based Cross-Sectional Study.

Myotonic dystrophy type I (MDI) is the most common muscular dystrophy in adults. The main objectives of this study were to determine the prevalence of MDI in the Community of Madrid (CM) (Spain) and to analyze the use of public healthcare services; a population-based cross-sectional descriptive study was carried out on patients with MDI in CM and data were obtained from a population-based registry (2010-2017). A total of 1101 patients were studied (49.1% women) with average age of 47.8 years; the prevalence of MDI was 14.4/100,000 inhabitants. In the women lineal regression model for hospital admissions, being in the fourth quartile of the deprivation index, was a risk factor (regression coef (rc): 0.80; 95%CI 0.25-1.37). In the overall multiple lineal regression model for primary health care (PHC) attendance, being a woman increased the probability of having a higher number of consultations (rc: 3.99; 95%CI: 3.95-5.04), as did being in the fourth quartile of the deprivation index (rc: 2.10; 95%CI: 0.58-3.63); having received influenza vaccines was a protective factor (rc: -0.46; 95%CI: -0.66-(-0.25)). The prevalence of MDI in the CM is high compared to other settings. Moreover, having any level of risk stratification of becoming ill (high, medium or low) has a positive association with increased PHC consultations and hospital admissions.

Back to basics: likelihood ratios for olive and grass pollen specific IgE in seasonal allergic rhinitis.

Introduction: Specific IgE (sIgE) is merely a sensitization marker that cannot be used for allergy diagnosis if there are no associated clinical symptoms. As of 2023, there is still no evidence regarding the quantity of sIgE necessary to confirm or exclude clinical disease. Therefore, this study aimed to calculate cut-offs for sIgE, allowing us to effectively diagnose olive or grass pollen allergy and select allergenic immunotherapy (AIT) candidate patients in a region under high olive and grass allergenic pressure. Methods: An observational retrospective study consisting of the review of electronic medical records from 1,172 patients diagnosed with seasonal rhino-conjunctivitis and suspected allergy to olive or grass pollen. Symptoms correlated with sIgE to Poaceae and Oleaceae whole extracts and sIgE to genuine allergenic components were evaluated. Optimal cut-off values were calculated using receiver operating characteristic curves. Relevant clinical symptoms and AIT indications were taken into consideration when determining the clinical allergy diagnosis. Results: sIgE to Lolium showed the best area under the curve (AUC) for both diagnosis (0.957) and an indication of AIT (0.872). The optimal cut-off values for grass diagnosis and AIT indication were 1.79 kUA/L and 8.83 kUA/L, respectively. A value of 5.62 kUA/L was associated with a positive likelihood ratio (LR) of 10.08 set for grass allergy. Olea sIgE showed the best AUC for the diagnosis (0.950). The optimal cut-off for diagnosis was 2.41 kUA/L. A value of 6.49 kUA/L was associated with a positive LR of 9.98 to confirm olive pollen allergy. In regard to immunotherapy, Ole e 1 sIgE showed the best AUC (0.860). The optimal cut-off was 14.05 kUA/L. Ole e 1 sIgE value of 4.8 kUA/L was associated with a 0.09 negative LR to exclude olive AIT indication. Conclusions: The sIgE cut-offs found in this population under high olive and grass allergenic pressure reduce the gap between sensitization and clinical allergy, providing a new tool for the diagnosis of seasonal allergic rhinitis/asthma and helping to discriminate patients who will benefit from AIT.

Effectiveness and Safety of Ustekinumab in Elderly Patients with Crohn's Disease: Real World Evidence From the ENEIDA Registry.

BACKGROUND AND AIMS: Clinical trials and real-life studies with ustekinumab in Crohn's disease [CD] have revealed a good efficacy and safety profile. However, these data are scarcely available in elderly patients. Therefore, we aim to assess the effectiveness and safety of ustekinumab in elderly patients with CD. METHODS: Elderly patients [>60 years old] from the prospectively maintained ENEIDA registry treated with ustekinumab due to CD were included. Every patient was matched with two controls under 60 years of age, according to anti-tumour necrosis factor use and smoking habit. Values for the Harvey-Bradshaw Index [HBI], endoscopic activity, C-reactive protein [CRP] and faecal calprotectin [FC] were recorded at baseline and at weeks 16, 32 and 54. RESULTS: In total, 648 patients were included, 212 of whom were elderly. Effectiveness was similar between young and elderly patients during the follow-up. Steroid-free remission was similar at week 16 [54.6 vs 51.4%, p = 0.20], 32 [53.0% vs 54.5%, p = 0.26] and 54 [57.8% vs 51.1%, p = 0.21]. Persistence of ustekinumab as maintenance therapy was similar in both age groups [log-rank test; p = 0.91]. There was no difference in the rate of adverse effects [14.2% vs 11.2%, p = 0.350], including severe infections [7.1% vs 7.3%, p = 1.00], except for the occurrence of de novo neoplasms, which was higher in older patients [0.7% vs 4.3%, p = 0.003]. CONCLUSIONS: Ustekinumab is as effective in elderly patients with CD as it is in non-elderly patients. The safety profile also seems to be similar except for a higher rate of de novo neoplasms, probably related to the age of the elderly patients.

[Design of an HACCP program for a cocoa processing facility]. / Diseño de un programa de Análisis de Peligros y Puntos de Control Crítico en el proceso productivo de cacao en polvo en una industria alimentaria.

The HACCP plan is a food safety management tool used to control physical, chemical and biological hazards associated to food processing through all the processing chain. The aim of this work is to design a HACCP Plan for a Venezuelan cocoa processing facility.The production of safe food products requires that the HACCP system be built upon a solid foundation of prerequisite programs such as Good Manufacturing Practices (GMP) and Sanitation Standard Operating Procedures (SSOP). The existence and effectiveness of these prerequisite programs were previously assessed.Good Agriculture Practices (GAP) audit to cocoa nibs suppliers were performed. To develop the HACCP plan, the five preliminary tasks and the seven HACCP principles were accomplished according to Codex Alimentarius procedures. Three Critical Control Points (CCP) were identified using a decision tree: winnowing (control of ochratoxin A), roasting (Salmonella control) and metallic particles detection. For each CCP, Critical limits were established, the Monitoring procedures, Corrective actions, Procedures for Verification and Documentation concerning all procedures and records appropriate to these principles and their application was established. To implement and maintain a HACCP plan for this processing plant is suggested. Recently OchratoxinA (OTA) has been related to cocoa beans. Although the shell separation from the nib has been reported as an effective measure to control this chemical hazard, ochratoxin prevalence study in cocoa beans produced in the country is recommended, and validate the winnowing step as well

Management of Double Sensitization to Vespids in Europe.

Wasp allergy with a diagnostic profile of double sensitizations to vespid venom is a frequent clinical problem in areas where different genera of wasps are present. Identification of the insect responsible for serious reactions poses a diagnostic challenge as the only effective treatment to date is immunotherapy based on the specific venom. In southern Europe, the double sensitization to Vespula and Polistes venoms is highly frequent. It has been shown that the major allergenic proteins (Phospholipase A1 and Antigen 5) share sequences across the different genera and species, which would be the cause of cross-reactivity. Additionally, the minor allergens (Dipeptidyl-peptidases, Vitellogenins) have been found to share partial sequence identity. Furthermore, venom contains other homologous proteins whose allergenic nature still remains to be clarified. The traditional diagnostic tools available are insufficient to discriminate between allergy to Vespula and Polistes in a high number of cases. IgE inhibition is the technique that best identifies the cross-reactivity. When a double sensitization has indeed been shown to exist or great uncertainty surrounds the primary sensitization, therapy with two venoms is advisable to guarantee the safety of the patient. In this case, a strategy involving alternate administration that combines effectiveness with efficiency is possible.

Natural and Induced Tolerance to Hymenoptera Venom: A Single Mechanism?

Inducing tolerance in Hymenoptera-allergic patients, bee venom immunotherapy (BVIT) is a widely accepted method to treat severe allergy to bee stings. In order to increase the existing knowledge on the underlying immunological mechanisms and look for possible biomarkers predictive of efficacy, a group of 20 bee-venom-allergic patients (AG) were thoroughly examined during their first year of BVIT. In addition, the results of treated patients with those of an untreated group of 20 tolerant beekeepers (TG) who had previously shown a firm suppressor-regulatory profile were compared. Tolerance in AG patients was invariably associated with a significant regulatory response characterised by the expansion of Helios- subpopulation and increased IL-10, specific IgG4 (sIgG4), and kynurenine levels. Although specific IgE (sIgE) levels increased transiently, surprisingly, the T helper type 2 (Th2) population and IL-4 levels rose significantly after one year of immunotherapy. Thus, the picture of two parallel phenomena emerges: a tolerogenic response and an allergenic one. Comparing these results with those obtained from the TG, different immunological mechanisms appear to govern natural and acquired tolerance to immunotherapy. Of particular interest, the kynurenine levels and T regulatory (Treg) Helios- population could be proposed as new biomarkers of response to BVIT.

Association of golimumab trough concentrations during maintenance with clinical, biological, endoscopic and histologic remission in patients with ulcerative colitis.

BACKGROUND: Optimal golimumab concentration thresholds for important outcomes during maintenance are lacking. AIMS: To investigate the association of golimumab trough concentrations during maintenance with key outcomes, including endoscopic and histologic remission, and long-term event-free persistence with golimumab, in patients with UC. METHODS: This multi-centre, cross-sectional study included patients with UC on golimumab maintenance recruited either in remission or during a flare. Colonoscopy was scheduled, and study-specific rectocolonic biopsies were taken for blind central histologic reading. Samples for golimumab trough concentrations were collected close to colonoscopy. RESULTS: Fifty-two patients were included. Median golimumab trough concentrations (µg/ml) were significantly higher in patients who had clinical remission (2.01 vs. 0.72, p = 0.047), combined clinical-biochemical remission (PMS ≤2 + faecal calprotectin <250 µg/g) (2.21 vs. 1.47, p = 0.041), endoscopic healing (Mayo endoscopic subscore 0) (2.52 vs. 1.47, p = 0.003), histologic remission (Geboes index ≤2.0) (2.33 vs. 1.50, p = 0.02) and disease clearance (clinical remission endoscopic healing + histologic remission) (2.52 vs. 1.70, p = 0.009), compared with those not meeting these criteria. Golimumab concentrations were significantly higher in patients who avoided golimumab dose escalation/discontinuation during follow-up (2.24 vs. 0.98, p = 0.012). Receiver-operating characteristic analyses identified golimumab thresholds [area under the curve] of 0.85 [0.76], 1.90 [0.76], 2.29 [0.75], 1.79 [0.68], 2.29 [0.72] and 1.56 [0.71] µg/ml as associated with clinical remission, combined remission, endoscopic healing, histologic remission, disease clearance and long-term event-free persistence with golimumab, respectively. CONCLUSIONS: Golimumab trough concentrations during maintenance are associated with favourable treatment outcomes including endoscopic healing, histologic remission and long-term persistence on golimumab. We identified the optimal golimumab thresholds most closely associated with key outcomes.
